When you are in the League Tables section, and change between the
following display categories: Simple, Traditional, Mathematical, and
Recent form - the new view of the table does not display when you click
the button beside the category name to invoke it.

To get the new view of the table to display you need to click the
'refresh' button (IE) or 'Reload Current Page' (Firefox) on your
browser toolbar.

This is a bug that seems to happen intermittently, and to date the web development team can't quite figure out how to sort it.
